DC-ATE, in the report they seem to think that had the flaps remained @ 30 they would have landed 50m sooner, and ploughed through various antennae.
The effect of this has not been calculated, but it is being assumed substantial damage may have been caused to the airframe.
So, like so many aspects of this approach, including the "fixation" of some that they reduced below best L/D, missed the autopilot etc etc, generally held wisdom was not recognised/ acted upon, but the final conclusion ? Result !
So WTH ?
